Preamble
|
|
--------
|
|
|
|
In this directory you can find some nice scripts and code that makes
|
|
using MPlayer and MEncoder easier, for example scripts for DVD track
|
|
encoding in three pass mode or creating SVCDs from a movie.
|
|

dvd2divxscript.pl
|
|
|
|
Author: Florian Schilhabel
|
|
|
|
Description: Yet another DVD to divx helper script.
|
|
This script encodes a DVD track in three pass mode to MPEG-4 with
|
|
libavcodec. Optionally it writes the resulting movie file to
|
|
CD-ROM the corresponding audio track to MP3. It can also shut
|
|
down the computer when it finishes. If you like, you can
|
|
watch the MEncoder output on /dev/tty8.
|
|
|
|
Usage: --help show help
|
|
--abr (AudioBitRate) Please enter the desired bitrate this
|
|
can be either [96|128|192] kbit/sec (default: 128).
|
|
--lang Specify the Language of the audio track this can be
|
|
for example <en> or <de> (default: <de>).
|
|
--dvd Specify the DVD track you want to encode.
|
|
--cdsize Specify the size of your CD-ROM (default: 700MB).
|
|
--shutdown Shutdown the system, when the encoding process has
|
|
finished. Needs appropriate privileges.
|
|
--out Specify the name of your encoded movie. The file
|
|
extension will be appended automatically.
|
|
--writecd Takes the newly created movie and writes it to a
|
|
CD-ROM.
|
|
--writedev cdrecord device identifier, for example 0,1,0
|
|
--speed writing speed (default: 4)
|
|
--dvd-device device to pull the video off (default: /dev/dvd)

aconvert

Description: A hack to allow MEncoder to read respectively encode from audio
|
|
only files.
|
|
|
|
Usage: aconvert <"input file"> <"output file"> <"options">
|
|
If no options are specified the following is assumed:
|
|
-oac lavc -lavcopts acodec=mp3:abitrate=192
|
|
|
|
Note: The script is probably bash dependent and it's just a quick
|
|
hack, feel free to improve it (or much better: fix MEncoder ;).

Tech scripts in the TOOLS dir

-----------------------------

|
|
|
calcbpp.pl
|
|
|
|
Author: Moritz Bunkus
|
|
|
|
Description: A script that calculates the $bpp for a movie, mentioned in
|
|
DOCS/tech/encoding-tips.txt, see that document for more info.
|
|
|
|
Usage: calcbpp.pl <resolution> <aspect ratio> <bitrate> <fps>
|
|
resolution: the cropped but unscaled resolution
|
|
(use '-vf cropdetect')
|
|
aspect ratio: the encoded aspect ratio. All DVDs come at
|
|
720x576 but contain a flag that tells the player
|
|
wether it should display the DVD at an aspect
|
|
ratio of 4/3 (1.333) or at 16/9 (1.777). Have a
|
|
look at MPlayer's output - there's something
|
|
about 'prescaling'. That's what you are looking
|
|
for.
|
|
bitrate: the video bitrate in kbit/s
|
|
fps: the fps
|
|
|
|
example: calcbpp.pl 720x440 16/9 896 25
|
|
|
|
|
|
countquant.pl
|
|
|
|
Author: Moritz Bunkus
|
|
|
|
Description: Counts the quantizers used for the encoding, mentioned in
|
|
DOCS/tech/encoding-tips.txt, see that document for more info.
|
|
|
|
Usage: countquant.pl < divx2pass.log
|
|
It will print out which quantizer was used how often. If you see
|
|
that e.g. the lowest quantizer (vqmin=2) gets used for > 95% of
|
|
the frames then you can safely increase your picture size.
|
|
|
|
|
|
plotpsnr.pl
|
|
|
|
Author: Jonas Jermann
|
|
|
|
Description: Draw PSNR log graphs using gnuplot.
|
|
|
|
Usage: plotpsnr.pl [options] <file>
|
|
-h, --help Display this help message
|
|
-quant Display quantizers
|

-size Display size
|
|
-psnr Display PSNR
|
|
-iframes Display I-frames
|
|
-pframes Display P-frames
|
|
-bframes Display B-frames
|
|
-aframes Display all frames in different colors
|
|
-cmp <file2> Compare two files
|
|
-qs <style> Quantizer style
|
|
-ss <style> Size style
|
|
-ps <style> PSNR style
|
|
|
|
Default: -quant -size -psnr -qs "p" -ss "i" -ps "p"
|
|
|
|
Note: Requires gnuplot. Comparison is based on file2. Comparison
|
|
assumes that the frame numbers of both files fit.

psnr-video.sh
|
|
|
|
Author: Matthias Wieser
|
|
|
|
Description: Calculates the PSNR between two existing video files.
|
|
The PSNR is calculated frame by frame.
|
|
Also prints the overall PSNR.
|
|
The script can be used to:
|
|
* Compare different softwarescalers (should I use
|
|
-sws 1 or -sws 2 ?)
|
|
* Compare different resolutions (is it better to scale
|
|
down to 640x360 or to 560x320)
|
|
* Compare different deinterlacers
|
|
* Compare different video codecs
|
|
* Compare video filters (is it better to use -vf hqdn3d
|
|
or lavcopts:nr=400)
|
|
* [...]
|
|
|
|
Usage: psnr-video.sh <file1> <file2> [<frames>] [<options1>] [<options2>]
|
|
|
|
<file1> and <file2> are the video files for which the PSNR
|
|
should be calculated.
|
|
[<frames>] is the number of frames to process, starting
|
|
from frame 1.
|
|
[<options1>] are additional MPlayer options for <file1>
|
|
[<options2>] are additional MPlayer options for <file2>
|
|
|
|
A file called ./psnr.dat will be created with the following

|
PSNR:;35.9887
|
|
|
|
Note: This script relies on the the tool "pnmpsnr" for the
|
|
frame-by-frame PSNR calculation.

realcodecs/
|
|
|
|
Author: miscellaneous
|
|
|
|
Description: Wrappers for Linux Real binary codecs used to analyze, alter and
|
|
dump the data flow between RealPlayer and its codecs.
|
|
|
|
Usage: - Set the path to the RealPlayer codecs directory in the C files.
|
|
- Run 'make realcodecs'.
|
|
- Rename the original codecs to match the names expected in the
|
|
wrapper sources. The default is to give them a "real" prefix,
|
|
e.g. realcook.so.6.0.
|
|
- Put the wrappers in the RealPlayer codecs directory.
|
|
|
|
Notes: Known to work at least on Linux x86 with RealPlayer8.

netstream - access remote streams
|
|
---------------------------------
|
|
|
|
NOTE: netstream does not link at the moment - help welcome.
|
|
|
|
netstream allows you to access most MPlayer stream types from a remote host.
|
|
The main purpose of this feature is to make it possible to directly use the
|
|
CD or DVD drive of another computer on the network (provided you have the
|
|
required bandwidth). On the downside some stream types (currently TV and MF)
|
|
are not usable remotely because they are implemented at the demuxer level.
|
|
|
|
Be aware that currently the server is not secure at all.
|
|
|
|
Compile the server by running 'make netstream' and then copy the netstream
|
|
binary to the right place on your system (usually /usr/local/bin on Unix).
|
|
Start the netstream server on the computer you intend to access remotely.
|
|
There are no command line arguments.
|
|
|
|
Play the second track of a VCD on the server with:
|
|
|
|
mplayer -cache 5000 mpst://servername/vcd://2
|
|
|
|
Access files on this server with:
|
|
|
|
mplayer -cache 5000 mpst://servername//usr/local/movies/lol.avi
|
|
|
|
Note that paths which do not start with a / will be interpreted as relative to
|
|
the directory where the server is running. The '-cache' option is not needed
|
|
but highly recommended.
|
